FileNotFoundError

[s108003854]

Hi~
I download the example data (neucon_demodata_b5f1) and run demo.py:

!python demo.py --cfg ./config/demo.yaml

I got the error message as below:

FileNotFoundError: [Errno 2] No such file or directory: './neucon_demodata_b5f1/images/00000.jpg'

I check the the folder as below and I find that this folder is indeed empty.

/neucon_demodata_b5f1/images

May I ask where this is probably going wrong?
